Had a woman do that when I was entering Trader Joes....:) :) ALL the way thru the parking lot, ALL the way thru TJs.....ROL.......talking about some REALLY private issues. Finally, at the last aisle, I joined in.."really, I'll be damned"..... all the while looking her straight in the eyes. She stopped and said "this is a private conversation". My response: "Really???? Could've fooled me, cuz we've all been privy to it all the way thru the store"....ROFLMAO.....when ALL the other customers started clapping, she turned red and left the store. :) :) :) :) my job was done.
